Liver function test

Our liver is one of the most important organs of the body and it is important that we keep a track of the liver health and monitor its function through regular tests. A liver functions test is a series of blood tests that help to diagnose and monitor a liver disease and damage. It measures the levels of enzyme and protein in your blood. Besides this, the liver function test also measures if the liver is doing its normal function of protein production and clearing the bilirubin which is the blood toxin.

When is a liver function test done?

  • A liver function test is done to screen for liver infections, like hepatitis
